RECEP'IAGLE FOR ELECTRIC LAMPS.

Specification of Letters Patent.

Patented Dec. 18, 1917.

Application filed July 8, 1914. Serial No. 849,755.

To all whom it may concern:

Be it known that I, AXEL V. OLsoN, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Receptacles for Electric Lamps, of which the following is a specification.

This invention relates to improvements in receptacles for electric lamps and has particular application to a sign receptacle.

In carrying out the present invention, it is my purpose to provide a receptacle of the class described which will be found especially useful in conjunction with sheet metal signs having apertures punched therein and arranged to form the characters of the sign and which may be readily set into the particular aperture and held therein against turning movement.

It is also my purpose to provide a receptacle of the type set forth which will be formed in such manner as -to receive the holding tongue or clip when in any position, thereby obviating the necessity for arranging the holding tongues in predetermined positions and enabling the circuit wires of the sign to be run in straight llnes.

A further object of my invention is to provide a lamp receptacle for electrically illuminated signs which may be manufactured and marketed at a minimum expense and applied to the sign and removed therefrom quickly and conveniently.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter setforth in and falling within the scope of the claim.

In the accompanying drawings:

Figure 1 is a face view of a" Sign plate having apertures punched therein and arranged to form a character showing the lamp sockets in position.

Fig. 2 is a fragmentary sectional view through the sign.

Fig. 3 is a view in side elevation of the receptacle removed from the sign.

Fig. 4 is a sectional view through the receptacle.

Fig. 5 is a similar view taken at right angles to Fig. 4.

Fig. 6 is a bottom plan view of the receptacle.

Fig. 7 is a perspective view of the cap removed from the body of the receptacle.

Fig. 8 is a plan view of the ca Herctofore, in punching holes, in the sheet metal, that form the letters or characters of the sign, it has been necessary to turn the sheet metal at different angles when forming the tongues or holding fingers on the walls of the apertures or openings in order to arrange the tongues in predetermined positions so that the latter will coincide with the notches in the respective receptacles set in the openings and hold the wire receiving grooves in such receptacles in alinement, thereby enabling the current carrying conductors of the sign to be run in straight lines. By means of my invention, I have eliminated the necessity for turning the sheet metal during the stamping thereof and the holding fingers or tongues on the walls of the apertures in the metal may be disposed in any positions, the receptacle being so formed as to receive the respective tongues in any position of the receptacle thereby enabling the wire grooves in one receptacle to aline with those of adjacent receptacles.

Referring now to the drawings in detail, 1 designates a sheet of metal having apertures 2 stamped therein and arranged to form the characters of the sign. Formed on the wall of each aperture 2 and extending into the latter is a holding tongue or finger 3.

The lamp .receptacle is indicated at 4 and, in the present instance, comprises an annular body 5 having a closed end 6 and an open end 7 Formed in the edge wall of the body at the open end thereof is an annular row of notches 8, while disposed within the body concentrically of the axis thereof is a. shell 9 stamped to form threads 10 on the inner and outer surfaces of the side Wall thereof. The bottom wall of this shell is suitably secured to the inner surface of the closed end 6. of the body, while disposed centrally of the shell and insulated therefrom is a contact l1. Formed in the outer surface of the closed end of the body are parallel wire receiving grooves 12 and located within one of the grooves 12 and electrically connected with the shell 9 is a binding screw 13, while disposed within the remaining groove and electrically connected with the contact 11 is a binding screw 14. 15 designates a cap com shell the flange l7 enters the space between the outer wall of the shell and the inner sur-' face of the side wall of the body 5.

In practice, the cap is detached from the body and the latter placed at the rear of the metal 1 in alinement withthe particular opening or aperture 2 therein, the shell 9 being projected through the opening, while the notched edge of the body abuts the rear surface of the metal around the aperture therein. The body is now rotated within the aperture until the wire receiving grooves 12 line up with the grooves in the bodies of adjoining receptacles. At this time the tongue 3 is forced into the adjacent notch on the body to maintain the latter against rotation within the aperture. The cap is now threaded onto the shell 9 and the collar 16 and notched edge of the body coact with From the foregoing description taken in connection with the accompanying drawings, the construction, mode of operation and mannerof employing my invention will be readily apparent. It will be seen that I have ceptacle comprisin provided a lamp receptacle for electrically illuminated signs of the sheet metal type which will be held to the metal against movement and whereby the holding tongue formed on the wall of the particular opening receiving the receptacle may be forced into locking engagement with the body of the receptacle irrespective of the position of the latter. I

While I have herein shown and described one preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claim without departing from the spirit of the invention.

I claim:

The combination with a supporting plate having an opening therein and a 'lug adjacent said opening, of an electric lamp rean annular body of insulating material avin a .closed end and an open end the edge 0 which is provided with an annular row of notches adapted to interchangeably receive said lug, an in-' teriorly and exteriorly threaded lamp contact shell within said body and secured to the bottom wall thereof, anda cap having a flange of insulating material provided with threads to engage the exterior threads on said shell and adapted to clamp the body in place against the sign late.

In testimony whereo I aflix in presence oftwo witnesses.
